How to repair drywall?

May 19, 2022

Sometimes, drywall can get damaged. Maybe you accidentally put a hole in it while moving furniture, or maybe your child got a little too enthusiastic with a crayon.

What often happens is that people try to repair the drywall themselves, but they don't quite know how. This can lead to an unsightly repair job that is noticeable to everyone who enters the room.

But don't worry - repairing drywall is not as difficult as it may seem. And even if you're not confident in your ability to do it perfectly, remember that drywall is pretty forgiving. A little bit of imperfection can easily be sanded down and painted over.

So, how to repair drywall? What you'll need:

Here's a step-by-step guide on how to repair drywall: But first let talk about what equipment you need.

  1. Putty knife
  2. Fine-grit sandpaper
  3. Drywall tape
  4. Joint compound
  5. Primer.

These are just a few of the essentials, but having the right tools will make your repair job much easier.

Now let's move on and get started with the repair.

1) Access the Damage

The first step is to assess the damage and figure out how big of a repair job you're dealing with. You'll also need to determine if the damage is structural or just cosmetic (Andrew Gaugler, Best of Machinery)

There are three main types of damage that can occur to drywall:

1. Holes

2. Cracks

3. Dents

Each type of damage requires a different repair method. Let's take a closer look at each one.

1. Holes

Holes in drywall are usually caused by accidents, like when you accidentally put a hole in it while moving furniture. Holes can also be caused by doorknobs, picture frames, or any other object that comes into contact with the wall.

2. Cracks

Cracks can be caused by a number of things, but the most common cause is settling. As your house settles, the drywall cracks. Cracks can also be caused by an earthquake or other seismic activity.

3. Dents

Dents are usually caused by something hitting the wall, like a fist or a piece of furniture. Dents can also be caused by objects falling from a height and hitting the wall.

Now that you have accessed and identified the damage, you can move on to the next step.

2) Choose the Right Repair Method

Once you have assessed the damage, you need to choose the right repair method. The repair method you choose will depend on the type of damage and the size of the hole, crack, or dent.

Here are some general guidelines:

Holes: For small holes (less than 4 inches in diameter), you can use a putty knife and joint compound to fill the hole. For larger holes, you will need to use a drywall patch.

Cracks: For small cracks, you can use a putty knife and joint compound to fill the crack. For larger cracks, you will need to use drywall tape.

Dents: For dents, you can use a putty knife and joint compound to fill the dent.

3) Prepare for the Patch

Now that you have chosen the right repair method, it's time to get started. The first step is to prepare for the patch.

If you're using a drywall patch, cut the patch to the appropriate size. If you're using joint compound, mix it according to the package directions (Chris Alexakis, Cabinet Select)

You need to make sure the area around the hole, crack, or dent is clean and free of debris. If there is debris, remove it with a putty knife. This way, the repair will be smooth and even.

4) Apply the Patch

Now it's time to apply the patch.

Start by attaching the drywall patch to the wall. Use drywall screws or nails to secure the patch in place.

Fill the hole with joint compound, using a putty knife.

Smooth the joint compound over the patch, making sure to feather the edges.

Allow the joint compound to dry. Once it's dry, sand the area smooth.

Apply a second coat of joint compound, if necessary and allow it to dry as well and sand the area smooth.

5) Add a Support (optional step)

If the damage is extensive, you may need to add support to the area. This will help to prevent further damage and make the repair stronger.

Cut a piece of drywall to the appropriate size and attach it to the wall with drywall screws or nails. Fill the area around the support with joint compound. This way, the repair will be stronger and less likely to fail. Allow the joint compound to dry and sand the area smooth.

6) Paint or Prime

The final step is to prime and paint the area. This will help to match the repair to the rest of the wall.

Use a primer designed for use on drywall. Apply the primer with a roller or a brush. Once the primer is dry, apply a coat of paint. Again, use a roller or a brush. Allow the paint to dry and here you go! Your drywall is repaired.

It must be looking exactly like new now!

Remember, when working with drywall, always take your time and be careful. It's easy to make a mistake and cause further damage. If you're not confident in your abilities, it's always best to hire a professional.

That's it! You now know how to repair drywall.
